Multi functional comprehensive electrical appliance

As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, which are eroded by factors such as sun exposure, rain, wind and sand, and humidity. Components, inverters, combiner boxes, cables and other equipment are prone to insulation layer aging and damage, grounding device corrosion and failure, which can lead to insulation performance degradation, grounding faults, leakage, short circuits and other safety hazards. This not only affects the normal operation of the power plant and reduces power generation efficiency, but also may cause major safety accidents such as electric shock, fire, and equipment burnout. Traditional testing tools have pain points such as single functionality, cumbersome operation, weak anti-interference ability, and inconvenient portability. Operations personnel need to carry multiple instruments back and forth for work, frequently switch equipment and wiring, resulting in low detection efficiency and difficulty in accurately locating fault points, which cannot meet the safety detection needs of the entire scene. Suzhou LAILX has been deeply involved in the field of new energy testing for many years. With the advantages of technological accumulation and industry university research cooperation, it accurately solves industry pain points and ingeniously creates the LXH601 insulation grounding comprehensive tester, achieving a comprehensive upgrade of photovoltaic electrical safety testing.

Integrated with multiple functions, significantly improving operational efficiency. LXH601 breaks the limitations of traditional testing equipment with "one machine, one use", integrating eight core functions including insulation resistance testing, grounding resistance testing, protective conductor conductivity testing, AC/DC voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location. It does not require frequent switching of equipment and wiring, and can complete multiple key tests in one operation, completely solving the problem of operation and maintenance personnel carrying multiple instruments to and from work. The efficiency of a single inspection has been improved by more than 40%. The device supports bipolar mode detection and can simultaneously measure the insulation resistance of the positive and negative poles of the circuit to ground, accurately evaluating the insulation status of the device; Equipped with polarity detection function, it can determine whether the polarity of the circuit wiring is correct and avoid reverse connection faults; Supporting insulation fault location, it can accurately locate the insulation fault points in the string, such as cable damage, junction box water leakage, etc., helping operation and maintenance personnel to quickly repair and reduce system downtime.

High precision detection technology ensures accurate and reliable data. LXH601 strictly follows the electrical safety testing standards of the photovoltaic industry, adopts high-precision testing circuits and anti-interference design, and can work stably in complex electromagnetic environments to avoid external interference affecting the testing results. The range of insulation resistance testing covers 0-1500V, suitable for the detection needs of high-voltage systems in photovoltaic power plants, with a measurement accuracy of ± 5%. It can accurately detect the insulation performance of equipment and timely detect hidden dangers such as insulation aging and damage; The grounding resistance test range is 0-200 Ω, with a measurement accuracy of ± 2%, which can accurately evaluate the reliability of the grounding device and prevent lightning strikes and electric shock risks; The conductivity test of the protective conductor can detect the continuity between the protective conductor and the equipotential conductor, ensuring electrical safety; The range of AC/DC voltage detection is 0-1000V, which can monitor the system voltage status in real time and detect voltage abnormalities in a timely manner. The equipment has been verified by authoritative institutions, and the detection data is accurate and reliable, which can serve as an important basis for safety assessment and operation records of photovoltaic power plants.

Portable and intelligent design, suitable for complex outdoor scenes. The LXH601 adopts a lightweight and compact design, with a small size and light weight. Paired with a dedicated portable bag, it can be easily carried by a single person to various photovoltaic power plant scenarios such as roofs, mountains, deserts, etc., without the need for multiple people to carry it, suitable for outdoor mobile detection needs. The device adopts a large-sized high-definition LCD display screen, a Chinese operation interface, clear and intuitive function menus, simple and easy to understand operation, and can be quickly mastered without professional training, greatly reducing the operating threshold. Equipped with a large capacity rechargeable lithium battery, it has a long battery life and meets the needs of all day outdoor testing. It supports battery level display and low battery reminder to avoid interruption of work. At the same time, the device has data storage and export functions, which can automatically save detection data, support one click export to the computer, generate detection reports, facilitate operation and maintenance data traceability, analysis and management, and adapt to the daily operation and maintenance, regular inspection, acceptance and testing needs of power plants.

Full scenario application safeguards the safety of photovoltaic power plants. In the daily operation and maintenance of photovoltaic power plants, LXH601 can regularly perform insulation and grounding tests on components, inverters, combiner boxes, cables and other equipment, timely detect and deal with safety hazards, and prevent accidents such as leakage and short circuits; During the installation and acceptance stage of the power station, the insulation performance and grounding reliability of the electrical system can be comprehensively tested to ensure that the power station construction meets safety standards; In the renovation of old power stations, the health status of the electrical system can be evaluated, providing scientific basis for equipment replacement and line optimization; In troubleshooting, insulation and grounding faults can be quickly located to assist maintenance personnel in efficient repairs and reduce power generation losses. In addition, the equipment can also be applied to electrical safety testing in fields such as power, industry, and construction, adapting to various high-voltage electrical system testing needs.

Suzhou LAILX always adheres to the development concept of "safety first, technological innovation". The launch of LXH601 insulation grounding comprehensive tester fills the gap of domestic photovoltaic electrical safety integrated detection equipment and provides efficient, accurate, and portable safety detection solutions for the photovoltaic industry.
